Raiden Miniatures will stop accepting orders for four weeks to work through their order backlog.
From their website:

Apologies to all but we will not be accepting new orders for the next 4 weeks. Our Ebay shop is now closed to new orders and won't open again till the 27th June. We don't really want to do this but due to your continuous over enthusiastic ordering this is the only way our we are likely to get our order back log cleared. If you can't wait a few weeks please remember that Doms Decals & Magister Militum stock our planes here in the UK.
